On saxophones, vibrato is produced by slightly lowering the bottom of your jaw and then raising it back up again in a repeating fashion while never actually losing contact with the instrument. What you are actually doing is lowering the pitch and then raising it back up again very quickly. By using vibrato, instruments are able to more precisely mimic the human voice and create a sound that is generally perceived as being more pleasing than a steady tone (although there are always exceptions). It also helps to mask minor intonation issues.

Playing with vibrato will not come to you quickly. It will probably take years for you to develop a consistently good vibrato. But saxophones can sound very ugly without it, so it is highly recommended that you get started with it as soon as possible.

There are multiple ways to perform vibrato. One is, as someone said to move your jaw slightly. Also, you can use your tongue, or you can also use your throat. You just have to experiment to see which method works best for you. Baritone Sax will be a little tougher because it's such a big horn, and takes a lot of air to fill it up.

There is nothing wrong with not using vibrato. It's better not to use it that to try to do it when you really don't know how. Use your ears and don't use the vibrato unless the music calls for it.
